Lets face it if GDW had realized what a complete disaster the Russians have turned out to be in the field they'd have rethought the premise for the game. However in the early 80's they seemed to be a serious threat.
Quite honestly the forces in numbers and total were evenly matched. The problem was positioning. The 8th Guards Tank Army and 1st Guards Army that followed it was facing just the V Corp in the Fulda Gap and it is (sort of) a channel towards Frankfurt.

.
So at the time the original game came out in the 1980s (I 1st played in Bamberg, GE in 1986) it seemed very plausible that the 2 large forces would grind each other down as the GDW game designers thought.
On the equipment side I have sent a couple of messages to our GM off list and I think all of your comments are valid. 2 themes are coming out, one this is the last shot of equipment before the big collapse and two it is very cold. My feedback is that if the gear is required the setting needs to remind us players of how dang cold it is, so we as the players are writing literally the cold is rattling the bones as our players man guard posts and the like.
I would not drop out yet, lets give our GM time to consume the feedback and make adjustments. He is new and he is really trying with the game.
